There was an ONVIF/RTSP battery camera I wanted, but nobody seems to have on the second-hand market... Netgear actually sold a rebranded/reflashed Arlo system as the FlexPower line with a special base station and reflashed Arlo cameras. The base did the magic that let the connected wireless Arlos act as ONVIF cameras in a DVR.
